The nRF5_SDK_14.2.0 of nRF52832 receive large data from android phone

Hi 

When I use the nRF5_SDK_14.2.0 of nRF52832, the example is selected ble_app_uart.  And the Android example is the Android_UART_Client_Bluethoot_Sensor_Nordic_CortexM4_NRF52832, but now the problem is that the nrf52832 device could finish receiving 5KB data from android phone after 7 seconds.  But according nordic test report the data rate cannot so slow. So could you give me some advice. Thanks.

Hi

The data throughput when transferring data from a phone to the nRF52832 will depend on a number of different factors:

- The phone being used

- How the data is buffered and sent in the Android app

- The connection parameters used (connection interval, slave latency)

- The MTU size used

Have you asked the author of the example what kind of speeds you should expect?
This is not a Nordic example, so that is not something I can comment on. 

But according nordic test report the data rate cannot so slow.

Which Nordic test report are you referring to?

Best regards
